WARNING

Depressurize First

Any time you remove/install/change a nozzle, you

must depressurize hose line by squeezing the spray

gun trigger while the motor is off. Even if the motor

has been off for a long period of time, the hose may

remain dangerously pressurized.

1. Make sure the motor is off and the hose line is

depressurized.

2. To install the nozzle, pull the collar back and twist

the nozzle firmly into the coupler on the end of the

wand.

3. Release the collar, making sure it springs back and

re-seats to its original (non-retracted) position.

Check the connection by pulling on the nozzle to

ensure a tight connection -- if correctly inserted,

nozzle will rotate but not pull out.

Prime the Water Supply

Turn On Water Supply and Squeeze the

Trigger

• Turn on the water supply. Make sure the water

supply is steady and flowing at a rate 20% over the

rated flow of your pump. (Reference the flow rate

table under the “Connect Hoses, Water Supply, and

Nozzle" section.)

Purge air from the water supply hose by squeezing

the trigger until a steady stream of water flows out of

the nozzle at low pressure. (Air in the hoses can

cause damage to the pump, so always make sure all

the air is out of the hoses before starting the

pressure washer motor.)

• Make sure the water supply hose is not kinked. A

kinked hose will provide insufficient water supply to

the pump and reduce its life. Make sure the hose

remains unkinked after moving the pressure washer.

Set Up for Chemical Spray (if desired)

Prepare for Chemical Spray (if planning to

use)

Using the proper cleaning chemical for the application

can speed up cleaning jobs tremendously.

Your pressure washer is equipped with a chemical

injection point on the downstream side of the pump for

introducing cleaning chemicals into the water stream. A

braided chemical hose is provided to connect at this

point. Suction pressure at this connection automatically

draws the chemical solution in through the hose, mixing

in 1-part chemical to 15 parts water. Adequate suction

pressure is created only when the low pressure (black)

spray nozzle is used.

The introduction of cleaning chemicals via the chemical

injection point affords the following advantages:

• It protects the pump from damage because no

chemical passes through the pump.

• It mixes the cleaning chemical into a low-pressure

spray. Cleaning chemicals applied under low

pressure adhere better to the surface being

cleaned, allowing the formula time to react and

remove dirt more effectively.

Note: An external upstream chemical injector is not

recommended for use with this pressure washer,

and if used would obviously alter the 15-to-1

dilution ratio and may cause pump damage.

CAUTION

Chemicals Containing Muriatic Acid

Certain chemicals, such as bleach or those containing muriatic

acid, will cause pump damage if introduced upstream through

the pump's water inlet. Use of chemicals not intended for

pressure washers will void pump warranty.

Acquire Cleaning Chemical

Use only approved pressure washer chemicals or

chemicals specifically formulated for use with pressure

washers.

CAUTION

Non-approved Chemicals

Non-approved chemicals can damage pressure

washer components (seals, wand, hoses, pump, etc.)

and be harmful to the environment.

Prepare for Chemical Spray (If Planning to Use)

Prepare the pressure washer for chemical spraying

using the following steps:

1. Prepare (dilute) chemical cleaning solution as

required for the job.

Note: the chemical solution will be automatically

mixed with the water at a ratio of 15 parts water to

1-part chemical solution.

2. Press the braided chemical hose over the chemical

injector and connect to the quick connect outlet.

3. Submerge the suction strainer connected to the

braided chemical hose into a bucket containing the

chemical solution.

WARNING

Chemical Spraying

• Never spray acids, corrosives, or abrasive or flammable

liquids. Breathing hazards, surface burns/corrosion, or

fire/explosion could result.

• Follow the chemical manufacturer's label instructions for

proper use and handling of the chemical. Understand all safety

hazards and first aid for all chemicals being used. Always wear

protective gloves when handling and cleaning with chemicals,

and wear other protective gear as directed by chemical

manufacturer. Always dispose of hazardous fluids per local,

state, and national guidelines.
